Abstract

An antenna apparatus has a first antenna branch and a second antenna branch. Both the first and the second antenna branch are in the form of a conductor loop which is not closed, and the first antenna branch is arranged at a distance from the second antenna branch in a direction which is substantially at right angles to the surface bounded by the respective conductor loop, such that the first loop direction, which is defined from the foot point to the free end of the first antenna branch, is arranged in the opposite direction to the second loop direction, which is defined from the foot point to the free end of the second antenna branch.
